TLP3481
Photocouplers Photorelay TLP3481
1. Applications
• ATE (Automatic Test Equipment) • Measuring Instruments • High-Speed Logic IC Testers • High-Speed Memory Testers 2. General
The TLP3481 photorelay consists of a photo MOSFET optically coupled to an infrared LED.
It is housed in a P-SON4 package. The TLP3481 features a very small on-resistance and on/off switching
of current as high as 3 A, making it ideal for switching applications in high-speed testers. 3. Features
